SUP 2.2 consumption of web service via MBO

I have an anonymously accessible internally deployed web service. I can consume it via the Eclipse SDK, transform it through XSLT, and can call it in an iOS application. The web server is being called, and returning data. I can see the activity as well in the SUP logs, in particular my data. The ONLY error I see is this:

2014-03-25 13:23:57.309 ERROR DataServices Thread-208 [com.sybase.vader.core.ToolingType]1d11e940-acd5-122d-8000-a820662492a8 xxxxxxxxxxxxxxxxxxxxx (Thread-208) com.sybase.vader.core.ToolingType::translateFromToolingName:42 - Tooling data type name is not specified - defaulting to String.

I've not seen that error before, so it may be related. Also, if i put a companion SAP MBO into the project, it does retrieve data down to the client, so I know my end-to-end code is fine.

Any thoughts?

Thanks,

Daryl
